Yes, saving energy is cheaper than making energy.

Utilities have options when it comes to meeting customer demand for electricity. They can build power plants to convert fossil fuels to energy. They can capture renewable resources like solar and wind. And they can work with residents and businesses to lower demand by implementing energy efficiency programs.

Unlike a solar panel installation or a natural gas plant, you might not see energy efficiency on your daily commute. But it’s a very real resource with a very compelling reason for utilities to invest in it: it’s typically the lowest-cost way to meet customers’ energy needs. By helping customers install efficient appliances, insulate their homes and buildings, and refine operations and maintenance practices, utilities are investing in the lowest cost energy resource out there.

Levelized Cost of Energy Resources

Energy efficiency programs aimed at reducing energy waste cost utilities less than three cents per kilowatt hour, while generating the same amount of electricity from sources such as fossil fuels can cost two to three times more. This isn’t a surprising result. Energy efficiency has remained consistent as the lowest-cost resource over the past decade even as program administrators have become more ambitious, capturing more energy savings in more markets and in more creative ways.

Investments in energy efficiency can have a big effect. In fact, in the Pacific Northwest, over half of the region’s growth in demand for electricity since 1978 has been met with energy efficiency. By choosing this low-cost resource, utilities have saved customers about $3.75 billion per year.

Energy efficiency has a host of other benefits, too. It’s clean, readily available, and reliable. It can increase comfort in homes and offices, and spur economic development in cities and towns. Utilities that invest in energy efficiency do so because it makes financial sense for them, but the payoffs accrue to everyone.
